In No. 1 doubles, Wallerich and partner Allison Harvey battled to a 6-4 first-set victory against Cotter's Lauren Renk and Elizabeth Cooper. But in the second set, Wallerich and Harvey struggled to get going, falling behind 2-1.

"We always get in a dip," Wallerich said. "We always pull ourselves back up because we have to tell each other to stay calm."

While the senior pair has been together for just this season, Wallerich and Harvey have known how to work well together.

"You just know little trigger things that will make them mad or when they're down or they're doing something wrong," Harvey said. "You know what they're thinking."

After trailing, the Tigers' No. 1 duo won the next five points to take the 6-2 second-set win to clinch the match.

Lake City has six days to prepare before its next match in the section playoffs, taking on No. 3-seeded Cannon Falls on Tuesday in Owatonna. The Bombers advanced with a 6-1 victory over No. 6 seed Trinity School at River Ridge on Wednesday.
